Cisco SLM2005 5-Port 10/100/1000 Gigabit Smart Switch with PD and AC Power Review

I purchased a SLM2008 8 port Managed Gige switch and two SLM2005 5 port Gige
switches. I am running a Cisco WS-G3550T-24 (24 ports Gige TX, and 2 Gbic slots)
as a central house switch that connects to a WS2950T-24 with two GigE-TX ports as
uplinks to the 3350. I am running QOS end to end for my VOIP PBX and Linksys PAP2T
analog 2 port FXS adapters for analog DECT 6.0 cordless phones. What I liked about
the Linksys devices is they are 802.3af 15V POE compliant which is great for powering
POE phones.
However in under 4 months one of the 5 port devices went bad. I ordered another
immediately as I didn't have a spare, and sent it in for repair. Now two months
later I have a second bad 5 port SLM2005 go bad. This one was hanging off my
2950T-24 and when the switch went, it destroyed the Gbic Phy chip on port Gige0/1
on my Cisco 2950T-24 switch :(
This is too bad. The first failure was after performing perfectly for 3+ months
at 1000Mbs Full Duplex, all of a sudden port 3 and 4 could not handshake. Then I
lost port 5. A 2 port Gige switch is fairly useless. On the second 5 port SLM2005
there was a fault in the power circuit. I noticed electrolytic leakage on one of the
capacitors in the power section. When it went, it killed the SLM2005 and it took
the GigE Phy chip in my Cisco 2950T-24 switch with it.
Ironically I have spares for the 3550 switch, and I can pick up another 2950T-24 as they
are only about $200 on the used market. My firewalls are Dual Juniper GS5. I guess it pays
to stick with the good stuff. I mean the 2950 Switches are almost 10 years old and you
normally can't kill them. The linksys Gig switches I would classify as Junk sadly.
But I rather bite the bullet now, spend the money and have it last then replace these
cheap knock-off's every few months.

D-Link DHP-301 Powerline HD Ethernet Kit Review

I was hoping to get at least 30 Mbps from my office to my living room (to stream HDTV, etc). I couldn't find any reviews for the D-Link version of Powerline HD but saw PC Mag and CNET reviews of the Netgear version. They were getting 45-53 Mbps in their test labs (theoretical max is 200Mbps). The D-Link kit was $60 cheaper so I decided to give it a try since I've had decent luck with other D-Link gear.
I have a 30 year old home so it's far from ideal test lab conditions. In my best case scenario where I plug the two adapters in consecutive outlets (8 feet apart), I get 48Mbps (avg). If I connect the adapters to the same circuit (i.e. outlets sharing the same circuit breaker), I get 20Mbps (avg). If I connect across two different circuits, I get 11Mbps (avg). Since HD streaming needs a solid 20Mbps, this won't meet my primary objective. However, it could extend my wireless broadband connection (5Mbps) if I choose to keep it. I may try out the Netgear version but I really doubt it would perform any better for me.
Pros:
-Very easy setup (adapters find each other in 15 sec)
-Kit comes with ethernet cables
Cons:
-Only 11-20Mbps (or 1.4-2.5 MB/s) in my home
-Adapters run pretty warm
Tips:
-Don't plug into any kind of surge protector or multi-outlet
-Connect the adapters on the same electrical circuit for max throughput
